Last night, Europe moved their clocks forward an hour and welcomed (Western|Central|Eastern) European Summer Time and this reminds me of my favorite DST map. Buckle up for the ride, as narrated by CGP Grey, and be ready to change your clocks a few times!

While Arizona ignores DST, the Navajo Nation inside of Arizona follows it. Inside of the Navajo Nation is the Hopi Reservation which, like Arizona, ignores daylight saving time.

Going deeper, inside of the Hopi Reservation is another part of the Navajo Nation which does follow daylight saving time.

And finally there is also part of the Hopi Reservation elsewhere in the Navajo Nation which doesn't. So driving across this hundred-mile stretch would technically necessitate seven clock changes!
